Title:
COOLING APPARATUS
Document Type and Number:
Japanese Patent JP3674791
Kind Code:
B2
Abstract:
PURPOSE: To enhance a cooling efficiency of a cooling apparatus, which comprises a combination of a cold accumulation type refrigerator and a cooling circuit, by means of a cold accumulator.
CONSTITUTION: A portion of a cold accumulator 3 changing from high temperature to low temperature by virtue of a working medium flowing in a cold accumulation type refrigerator 11 is brought into heat contact with a cold transfer heat exchanger 21 in a circulation circuit 27, which causes a working medium other than the working medium in the cold accumulation type refrigerator 11 to circulate between it and an object 25 being cooled, or a counterflow heat exchanger whereby the working medium flowing in the cold accumulator 3 in one cycle from high temperature to low temperature and from low temperature to high temperature generates cold, so that it is possible to use cold for cooling the object being cooled, thereby enabling greatly enhancing a cooling efficiency.
